Millions of years ago, a fallen or dead tree was buried in sediments, including a considerable amount of volcanic ash. Overtime, the mineral rich water from the soil will replace the organic cells of the wood with inorganic elements like carbon (black), cobalt (green/blue), chromium (green/blue), copper, (green/blue), iron oxides (red/brown/yellow), manganese (pink and orange), manganese oxides (black or yellow) and silica ( white/grey/blueish white) to name a few. Wood begins a petrification process once it is buried in sediments with very little exposure to oxygen. Streaks of warm browns and reds are indicative of iron oxides intermixing with quartz and other minerals during a specimen's fossilization process.Petrified wood is the common name for wood that has turned to stone.
